NYT today has an article on an issue of great importance to all science disciplines – data management. The article – “A Deluge of Data Shapes a New Era in Computing” overviews the new book published by Microsoft researchers – “The Fourth Paradigm: Data-Intensive Scientific Discovery.”

This is a hot issue in science libraries too, as we are trying to understand how to deal with the vast amounts of digital data and whether libraries have a role to play to support, maintain and archive some of this data…

Abstract: The atmospheric greenhouse effect, an idea that many authors trace back to the traditional works of Fourier (1824), Tyndall (1861), and Arrhenius (1896), and which is still supported in global climatology, essentially describes a fictitious mechanism, in which a planetary atmosphere acts as a heat pump driven by an environment that is radiatively interacting with but radiatively equilibrated to the atmospheric system. According to the second law of thermodynamics, such a planetary machine can never exist. Nevertheless, in almost all texts of global climatology and in a widespread secondary literature, it is taken for granted that such a mechanism is real and stands on a firm scientific foundation. In this paper, the popular conjecture is analyzed and the underlying physical principles are clarified. By showing that (a) there are no common physical laws between the warming phenomenon in glass houses and the fictitious atmospheric greenhouse effects, (b) there are no calculations to determine an average surface temperature of a planet, (c) the frequently mentioned difference of 33 degrees is a meaningless number calculated wrongly, (d) the formulas of cavity radiation are used inappropriately, (e) the assumption of a radiative balance is unphysical, (f) thermal conductivity and friction must not be set to zero, the atmospheric greenhouse conjecture is falsified.

“For all but a handful of the scientists he studies, the prestige of their institution pretty much determines their professional–and even their personal–destiny. Of the more than 4000 institutions of higher learning in the United States where a scientist can get a faculty post–ranging from world-renowned research universities to local community colleges–only a very limited number possess the resources, reputation, and connections needed for research careers at the highest levels of recognition.”

Personally, I would love to take some of the science classes such as :

The Science of Superheroes: While it might sound like fun and games, this course takes superheroes as a means to teach students real lessons about physics. [U of California Irvine] or Lego Robotics: Legos can help you build more than just that TIE Fighter, they can also be used to make real robots, as this course will show students. [MIT]

Good news regarding the UBC Library’s CISTI Orders Document Delivery Service. You no longer need to come to the Library to pick up your CISTI or Interlibrary Loan request.

For CISTI Orders articles, Interlibrary Loan staff are creating brief records in Relais (our ILL/DD software) in order to post the articles to the web and to send an email to the user. The article can be accessed a total of 3 times within 15 days from the date of the email message. After either accessing the article 3 times or 15 days have passed, the article is no longer available to the user.

Articles ordered from Interlibrary Loan are now being delivered to UBC users via post to web. When an article is received, Interlibrary Loan staff match the article to the correct request and then it is posted to the web. The user receives an email message with a link to the article. The user then clicks on the link to obtain the article. The user does not need a password to access their articles.

All articles received by 5:00PM Monday to Friday will be processed that day.

Under the Copyright Act, if the user wants to keep a copy of the article, they must print a copy. The article has been received for the purposoe of research or private study only. It is not for redistribution, retransmission or electronic storage. It cannot be used for any other purpose or reproduced without permission of the copyright owner.

arXiv.org mediates contact with the literature for entire scholarly communities, providing both archival access and daily email and web announcements of new materials. We confirm and extend a surprising correlation between article position in these initial announcements and later citation impact, due primarily to intentional self-promotion by authors. There is, however, also a pure visibility effect: the subset of articles accidentally in early positions fared measurably better in the long-term citation record. Articles in astrophysics (astro-ph) and two large subcommunities of theoretical high energy physics (hep-th and hep-ph) announced in position 1, for example, respectively received median numbers of citations 83%, 50%, and 100% higher than those lower down, while the subsets there accidentally had 44%, 38%, and 71% visibility boosts. We also consider the positional effects on early readership. The median numbers of early full text downloads for astro-ph, hep-th, and hep-ph articles announced in position 1 were 82%, 61%, and 58% higher than for lower positions, respectively, and those there accidentally had medians visibility-boosted by 53%, 44%, and 46%. Finally, we correlate a variety of readership features with long-term citations, using machine learning methods, and conclude with some observations on impact metrics and the dangers of recommender mechanisms.
